HOA boards call us most often for the parts of a neighborhood everyone sees: the community building, the entry sign, and the shared walkways. Across New Castle County, irrigation and well-water sprinklers leave orange rust stains on that concrete. At T&T Powerwash, we give your board a fast estimate and plan the timing with you. The invoice goes out once the work is done. Call (302) 415-3285 to get your entrance and walkways looking right again.
Boards bring us in for the pieces of a community that every resident drives past and every visitor notices first. Here is what we handle and how.

We soft wash the siding with a mild mix of SH (sodium hypochlorite) and surfactant, matched to the material. Clubhouses get the same care as the commercial buildings we wash. The landscaping around the building gets rinsed before we start and again when we finish.

Your entrance sign is the first thing anyone sees on the way in. Sprinkler-fed beds around a sign often leave rust behind, and we price rust removal only after testing a spot.

Shared concrete gets an even finish from edge to edge because we clean it with a flat surface tool instead of a wand. We use the same approach on concrete parking lots. A treatment afterward helps it stay bright longer. Blacktop is the one surface we leave alone.

Some boards want every roof or every house in the community done at once, and we run that as a single campaign. Homes get a soft wash with the plants protected. On roofs, we follow ARMA guidelines and rinse the shingles once the treatment has done its job.

We prioritize 55+ communities. If your association serves residents 55 and older, let us know when you first reach out.
Two things set our HOA work apart.

We clean five or six homes a day on community work. Each home still gets the same standard it would get if it were the only job on our schedule.

Plenty of HOAs never set money aside for exterior cleaning. We’ll still take the job, even when all your board needs is the sign at the front entrance.
Someone from the board calls, texts, or fills out our form. Tell us what’s bothering residents, whether that’s dirty roofs, stained houses, grimy walkways, or a faded entry sign.
We walk or drive the property and look at how the homes are sized if a campaign is on the table. We’ll ask about your budget so the dirtiest areas come first. You get a detailed, line-item estimate quickly, and we can send our COI and W-9 whenever your board asks.
We set the dates together with the board. For a campaign, each resident gets our Six Steps to Success prep checklist a few days ahead and a text when we’re on our way.
Our crew hooks up to water on site, and two working spigots make the day go smoother. Buildings and homes get our soft-wash system, with plants rinsed first and everything neutralized and rinsed after. On roofs, gutter bags catch the runoff. Walkways and shared concrete go under the surface cleaner, followed by a post-treatment.
We walk the finished work so anything you spot gets handled before we pack up. The invoice comes when the job is complete. We take check, ACH, credit card, or cash, and net 30 terms are available on request.

If something isn't right, tell us, on the day or three days later. We'll come back out, look at it with you, and make it right where cleaning can.
Most touch-ups get handled during the final walkaround. If a board member or resident notices something after we leave, a call brings us back.
Yes, an HOA can spread its exterior cleaning across the year by working through the neighborhood quarter by quarter. Many boards find that easier on the budget. If you want the same work done on a regular cycle, yearly contracts are available on request.
Most neighborhood campaigns run 25 to 50 homes and are typically scheduled across one to two weeks. Jobs limited to common areas, like a community building or an entrance sign, vary with the scope. We’ll give you a time frame with your estimate.
Estimates are free, and most can start from your community’s address and a couple of photos. Tell us what your board wants cleaned, and we’ll send a clear, line-item number back fast. Boards across New Castle County can call (302) 415-3285 to get on the schedule.
